This invention relates to separable fastenicrs of the ty e in which a plurality of mating and interloc l ring fastening elements are arranged along opposite edges of a closure, be ing brought together into interlocking condition by means ofa movable slider on cam member which opens or closes the fastener as the slider is moved .up or down along the closure. m The purpose of the present invention is to improve upon the slider construction so that it will be strengthened and reenforced in such a manner as to prevent spreading of the late's which constitute the body of the sli er. Heretofore various expedients have been suggested and used for the purpose of eliminating any spreading action ofthe slider,-

which results in faulty operation of the fastening elements.

The present invention has for its object the provision of a new and improved slider construction which Will give greater strength and resistance to spreading than prior forms. The results are o tained in an inexpensive and neat appearing construction WlilCh it is the purpose of the present application to cover, changes and modifications 'eing possible within the scope of the invention as set forth in the claims,

In the. drawings, in which the preferred form ofthe invention is shown: Figure 1 is a front viewv of a closure with my new and improvedform of slider thereon;

gigure2 is-a side view partly in section; an

Figure 3 is a section onthe line 33 of Figure 1a The closure consists locking and. mating elements which are secured to the edges of the opening, as illustrated in Figurel, in which a row of male elements'is indicated b the numeral 5 and a row of female elements y the numeral 6, the elements being brought locg ngagement bythe slider as is usual. 4 The particular desi of the interlocking elements is not essential to some aspects of the present invention, whichis directed more esracially to t e n u ti ntoithe slider- 6 t of a series of inter into mating and 'inter- The slider is" composed of 'two plates 7 and 7' 8 placed one above the other, the plates. being flanged along their outer edges' with the flanges projecting toward one another, as, shown at 10; The slider is formed with two diverging channels 12 and 13 for-the male and female members which merge into the single channel 14 throu h which the connected' fastener issues', t e aforementioned flanges guiding the slider over the interlocking'elements.

The upper portion of the plates are depressed to form triangular flat areas 18 which are placed in contact with one another and.

thereby space the wings throughout the channels. The areas at this point are extended upwardly-beyond the main body of the slider to afiord a greater area of contact between the plates. The apex 19 of the trian ular area is directed downwardly towar the channel 14 and operates as the spreader for separating the closures, it being observed thatadjacent the apex and along the walls of the trian ular spreader portion the channel 12, for t e male members 5, is restricted somewhat, as shown at 20, for guiding the prongs of the male'members so that they will properly enter the female members of the fastener.

The depressed triangular areas 18 between the channels 12 and 13 serve not only as a spreader or divider for the separable fastener, 'but also as a means forconnectingthe two plates which form the upper and lower plates of the slider, by means of a sta le 25, the ends of which maybe reduced to orm shoulders 26 hearing against the upper plate. The ends 27 of the staple are passed through the plates and riveted over to securely fasten the twoplates together, a hacking plate 28 being placed against the rear plate 8 more firmly to. secure the rivet in place. .By the provision of the stapled rivet as shown, the two plates are securely fastened and braced by the two points-of attachment which serve to prevent any rocking movement between the two plates. The upper edges of the trian lar area of each late are T011118 with a ange 31: extending om channel to c annel, which flange, operates as a further reenforcement or'brace for the plates constituting the slider.

The open head of the rivet'is used as a keeper for the operat tab 30 for the slider which is loosely pivote thereon.

It will be observed that a ve strong and economical construction of sli er has been devised, and one whicli is easy and inexpensive to manufacture and assemble.

between the two plates of the lider efiectually prevent spreadin between e plates and at the channels. Ihe triangular depressed areas on the slider also afiord an easy means of obtaining the pointed spreader which sepa' 7 rates the male. and female members of the said slider com risin tions of sai separable fastener. Other objects and advantages will be apparent from the description of the device, as will be understood and a preciated by those'skilled in the art. The P tlons and are therefore economical o manufacture. s' What is claimed is: y

1. A separable fastener comprising interlocking members'secured to the edges of a closure, and a slider to operate the closure, independent spaced plates forming 0 anne for the passage of the members, de resseda'r'eas in the upper porlates which areas are placed in contact, fastening means to secure the two plates together a'ssing through the areas, and reenforcing anges about the uppermargins of the areas 2. In a separable fastener, a slider comprising twometal lates of substantially even thickness throng out,rdepressed areas in said plates which are in contact and thereby space the balanceof the lates to form channels, the channel at one side of the depressed area comprising an enlarged and reduced opening leading one into the other in combination with matinginterlocking fasteners including male members which are guided bythe reduced channel and uppersides of-the de ressed areas.

3. In a separable astener, a slider comprisin two metal plates having depressed areas in contact, the remainder of the plates afiording channels for the assage of the members of the fastener, d about the upper sides of the depressed areas, and a rivet passin through the areas.

4. In a separab e fastener, a slider comprising two metal plates having depressed triangular areas in contact, the remainder of the plates affording channels for the passage of t e members of the fastener, a backin plate seated in one of the depressed areas, an

a stapled rivet passing through the areas and through the backing plate or retaining an operating tab.
